Subject: [PATCH v3 00/15] Enable CONFIG_VMAP_STACK on PPC32
Date: Tue, 10 Sep 2019 09:16:18 +0000 (UTC) [thread overview]
Message-ID: <cover.1568106758.git.christophe.leroy@c-s.fr> (raw)
The purpose of this serie is to enable CONFIG_VMAP_STACK on PPC32.
rfc v1: initial support on 8xx
rfc v2: added stack overflow detection.
v3:
- Stack overflow detection works, tested with LKDTM STACK_EXHAUST test
- Support for book3s32 added
Christophe Leroy (15):
powerpc/32: replace MTMSRD() by mtmsr
powerpc/32: Add EXCEPTION_PROLOG_0 in head_32.h
powerpc/32: save DEAR/DAR before calling handle_page_fault
powerpc/32: move MSR_PR test into EXCEPTION_PROLOG_0
powerpc/32: add a macro to get and/or save DAR and DSISR on stack.
powerpc/32: prepare for CONFIG_VMAP_STACK
powerpc: align stack to 2 * THREAD_SIZE with VMAP_STACK
powerpc/32: Add early stack overflow detection with VMAP stack.
powerpc/8xx: Use alternative scratch registers in DTLB miss handler
powerpc/8xx: drop exception entries for non-existing exceptions
powerpc/8xx: move DataStoreTLBMiss perf handler
powerpc/8xx: split breakpoint exception
powerpc/8xx: Enable CONFIG_VMAP_STACK
powerpc/32s: reorganise DSI handler.
powerpc/32s: Activate CONFIG_VMAP_STACK
